A. Magnetron Development

چکیده
To facilitate the construction of the high-power magnetron, the entire output section, including the quarter wave transformer and window, has been redesigned. The new design is based on standard S band waveguide. The quarter wave transformer was changed to increase the external loading of the tube. Cold test measurements on a tube with the redesigned output section give an external Q of 230. Work is in progress to build and test eight or more magnetrons. It is expected that all of these tubes will have ceramic cathode leads and that at least four of them will have thoria cathodes. The change to ceramic cathode leads will necessitate some slight redesign of the anode, and the change to the thoria cathode will require lengthening of the end spaces and further cold testing to detect and then eliminate possible spurious end space resonances.
